What is taking up my gigs on my iphone?

Ok so yesterday I got my new iphone5s and went on iTunes and checked my storage and it said that other took up 2 gigs. What is other for the iphone? How do you take of other.

The stuff that goes in "other" will depend on how you use your iPhone. One possible explanation is any app that relies on your use of the internet - safari being the obvious possibility. Try clearing the history and cookies for safari in settings, then doing a full restart.

Other is usually files from iOS itself as well as cache from apps. Other than clearing that cache every now & then nothing really could be done. You could download a desktop app called PhoneClean that could do it for you though. Works fine for me.

Thats basically the software (IOS 7, fingerprint) that makes your phone run. You can't delete it.
